Description

IN THE MATTER OF an Australian Application corresponding to PCT Application PCT/EP2004/000703 RWS Group Ltd, of Europa House, Marsham Way, Gerrards Cross, Buckinghamshire, England, hereby solemnly and sincerely declares that, to the best of its knowledge and belief, the following document, prepared by one of its translators competent in the art and conversant with the English and German languages, is a true and correct translation of the PCT Application filed under No. PCT/EP2004/000703. Date: 17 May 2005 C. E. SITCH Deputy Managing Director - UK Translation Division For and on behalf of RWS Group Ltd Novel crystalline modification of the anhydrate of boscalid The present invention relates to monoclinic 2-chloro-N-(4'-chlorobiphenyl-2 yl)-nicotinamide melting at 147 - 148 0 C and of the formula 1 5 0 '- N N CI CI The present invention furthermore relates to the preparation thereof: Monoclinic 2-chloro-N-(4'-chlorobiphenyl-2-yl)nicotinamide melting at 144 - 145 0 C and 10 of the formula I is described in EP-A-545 099 and PCT/EP02/10320 and is known under the common name boscalid. PCT/EPO2/10320 describes the anhydrate and the hydrate of boscalid and also the preparation of boscalid hydrate from boscalid anhydrate. 15 The known anhydrate of boscalid is referred to in this Application as modification I and the anhydrate of boscalid as claimed in claim 1 is referred to as modification 11. In order to prepare an aqueous suspension concentrate (SC) or a suspoemulsion (SE) from the anhydrate of boscalid, according to PCT/EP02/10320 it is first necessary to 20 prepare the hydrate of boscalid, which is then very finely milled in the presence of water and further assistants. This is not possible with the anhydrate of boscalid since, when this is milled with the assistants in water, it forms a loamy solid which hinders the further milling process. 25 According to PCT/EPO2/10320, the hydrate of boscalid of modification I is prepared by dissolving the anhydrate of boscalid of modification I in a water-soluble solvent and then precipitating the hydrate by adding water. Solid formulations, such as spray-dried or extruded water-dispersible granules, can be 30 prepared directly from the anhydrate of boscalid of modification I without having to carry out a conversion to the hydrate beforehand. If these water-dispersible granules are then diluted with water and are mixed with solvent-containing crop protection preparations, for example emulsion concentrates 35 (EC), problems may arise during application since boscalid crystals form and may then block the filters in application apparatuses.
2 It is an object of the present invention to eliminate the deficiencies described in the case of the water-dispersible granules. We have found that this object is achieved by providing the monoclinic anhydrate of 5 boscalid of the formula I of modification 11 which melts at 147 -148 0 C. Surprisingly, it was found that the anhydrate of boscalid of the formula I in the form of modification 11 shows scarcely any crystal growth in the presence of solvents. The preparation of the anhydrate of boscalid of formula I of modification I is described 10 in EP-A-545 099 and PCT/EP02/10320. The present invention furthermore relates to processes for the preparation of anhydrate of boscalid of modification 11. 15 In one embodiment (process 1), the process comprises the following steps: a) dissolution of the anhydrate of the compound of the formula I of modification I in a polar organic solvent or an aromatic hydrocarbon, 20 b) precipitation of the anhydrate of the compound of the formula I of modification Il by cooling the solvent. Suitable polar solvents are alcohols, glycols, ketones, ethers, esters, amides and mixtures of these solvents. Aromatic hydrocarbons are furthermore suitable. 25 Examples of alcohols are methanol, ethanol and propanol. Methanol is particularly preferred. Suitable glycols are, for example, ethylene glycol and diethylene glycol. 30 Suitable ketones are, for example, acetone and cyclohexanone. Suitable ethers are, for example, dioxane and tetrahydrofuran. 35 A suitable ester is, for example, ethyl acetate. A suitable amide is, for example, dimethylformamide. Suitable aromatic solvents are, for example, benzene, toluene and xylene. 40 3 The dissolution of the anhydrate of the compound of the formula I of modification I in stage a) is effected at from 20 to 1500C, preferably from 40 to 1150C, particularly preferably from 50 to 95*C. 5 The precipitation of the anhydrate of the compound of the formula I of modification Il in stage b) is effected by cooling the solution obtained in stage a) to temperatures of from 0 to 300C, preferably from 10 to 250C, particularly preferably from 20 to 250C. The precipitation is effected over a period of from 1 to 24, preferably from 2 to 20, hours. 10 The addition of seed crystals of the anhydrate of the compound of the formula I of modification 11 in stage b) is particularly advantageous, substantially accelerating the precipitation. In a further embodiment (process 2), the process comprises the following steps: 15 a) heating of the anhydrate of the compound of the formula I of modification I to above 1500C until everything has melted, b) cooling of the melt with addition of seed crystals of the anhydrate of the 20 compound of the formula I of modification Hl. The seed crystals are added in stage b) in an amount of from 0.01 to 20, preferably from 0.5 to 5, % by weight. 25 This process is preferably carried out in a suitable stainless steel vessel. The conversion of the anhydrate of the compound of the formula I of modification I into modification 11 takes place quantitatively. The physical properties of the two modifications of the anhydrates of the compound of 30 the formula I are compared in table 1: 4 Table 1 Properties Anhydrate, modification I Anhydrate, modification Il Molecular weight 342 342 [g/mol] Melting point [*C] (DSC) 144.8 147.2 Heat of fusion [J/g] (DSC) 85 106 Density [g/cm 3 ] 1.399 1.457 Characteristic IR bands 924, 1310, 1650 868, 917, 1675 [cml] 5 The cell parameters from the crystallographic investigations using a single crystal diffractometer from Siemens are shown in table 2: Table 2 10 Parameter Anhydrate, modification I Anhydrate, modification || Class Monoclinic Monoclinic Space group P21/c P21/c a 1479.2(3) pm 1162.5(6) pm b 1157.67(19) pm 1134.2(4) pm c 1872.1(3) pm 1283.2(5) pm a 90* 9 0 * P 91.993 (17)* 114.52(4)* y 900 90* Volume 3.2038(9) nm 3 1.5390 nm 3 Z 8 4 Density (calculated) 1.423 mg/m 3 1.481 mg/m 3 R', wR 2 0.1036; 0.1699 0.0489; 0.1264 The parameters shown have the following meaning: a,b,c = edge lengths of the unit cell 15 a,p,y = corresponding angles Z = number of molecules in the unit cell 5 Example 1: Preparation of the anhydrate of the compound of the formula I of modification 11: 5 30 g of methanol are initially taken in a conical flask having a ground glass joint. Thereafter, 5 g of anhydrate of the compound of the formula I of modification I are added and the mixture is heated to 550C in a water bath while stirring until everything has dissolved (about 10 minutes). Thereafter, the flask is removed from the heating bath and then left to cool for a period of 18 hours at ambient temperature (about 200C). 10 Anhydrate of the compound of the formula I of modification 11 crystallizes out. Melting point 147.2*C Example 2: 15 200 g of anhydrate of the compound of the formula I of modification I are heated to 1600C in a stainless steel vessel. The melt is then cooled while stirring. At 150"C, seeding is effected with crystals of the anhydrate of the compound of the formula I of modification 11 and cooling is continued. Anhydrate of the compound of the formula I of 20 modification 11 is obtained. Example 3: 25 Preparation of water-dispersible granules of anhydrate of the compound of the formula I of modification I or II: Composition: 30 Component Concentration Boscalid (active ingredient) 30 - 60% w/w Dispersant (ligninsulfonate salt) 10 - 20% w/w Wetting agent (naphthalenesulfonic acid 5 - 10% w/w condensate salt) Antifoam (silicone oil) 0.5 - 1% w/w Standardizing agent (sodium sulfate) to 100% 6 Preparation process: A suspension of suitable concentration is prepared and is milled to the desired particle size (50% < 2 pm) by means of a pearl mill. The suspension is then dried in a spray 5 tower. Comparison of the tank mixing compatibility: For this purpose, both water-dispersible granules of the above composition, comprising anhydrate of the compound of the formula I of modification I (formulation A), and water 10 dispersible granules of anhydrate of the compound of the formula I of modification II (formation B) were prepared. A 5% strength suspension of the respective water-dispersible granules in CIPAC D water (Ca**/Mg** (4:1) hardness of 342 ppm and pH of from 6.0 to 7.0) was then 15 prepared. This suspension was then mixed with 1% of Solvesso 200 (mixture of aromatic hydrocarbons) as a typical solvent for solvent-containing liquid formulations (e.g. EC). The corresponding spray liquor was then stored over a certain period at a certain temperature. For assessing the quality, the solid residue on a 75 pm sieve was determined after the storage. 20 Result Formulation Storage time Storage Residue on temperature 75 pm sieve A 24 hours 20 0 C 13.0 % w/w A 24 hours 30 0 C 14.3 % w/w A 7 days 20 0 C 16.8 % w/w A 7 days 30 0 C 19.3 % w/w B 24 hours 20 0 C 0.1% w/w B 24 hours 40 0 C Traces B 7 days 20 0 C Traces B 7 days 40 0 C 0.1% w/w
